I’m 87. Have lived with Trigeminal Neuralgia for 17 years. At first Tegretol helped a little but disease worsened and Tegretol damages liver. Went to legal Dronabinol(THC) with doc’s prescription. Insurance paid. CVS provided 2.5mg pill. THC Stopped pain, and no side effects. Also have tried CBD oil with 1200mgs per ounce. 2 drops sublingual. Not a good taste but I am without pain using CBD at 1200mgs per ounce. It also means I now have only a negligible amt of THC in my body.
Currently, the only CBD product approved by the Food and Drug Administration is a prescription oil called Epidiolex. It's approved to treat two types of epilepsy. Aside from Epidiolex, state laws on the use of CBD vary. While CBD is being studied as a treatment for a wide range of conditions, including Parkinson's disease, schizophrenia, diabetes, multiple sclerosis and anxiety, research supporting the drug's benefits is still limited.
